British NVC community W7

NVC community W7 (Alder-Ash-Yellow Pimpernell woodland) is one of the woodland communities in the British National Vegetation Classification system; it is one of seven woodland communities in the NVC classed as "wet woodlands".

Community composition

Alder is often not as abundant as in the previous types. Ash and/or silver birch are frequent with mixtures of common sallow, hazel and hawthorn in the shrub layer. Ground flora includes meadow sweet, yellow pimpernell, lady fern, rough stalked meadow grass, creeping soft grass, creeping buttercup and/or golden saxifage. These are found on base rich flushes with gleyed mineral soils.

Distribution

It is the commonest alder type in upland woods; it does occur in the lowlands but often in a rather fragmentary fashion along streams.
